Thank you. Try this:

Sub Convert2Date()
    Dim rng As Range
    Dim cel As Range
    Application.ScreenUpdating = False
    On Error Resume Next
    Set rng = Range(Range("D2"), Range("D" & Rows.Count).End(xlUp))
    rng.NumberFormat = "m/d/yyyy"
    For Each cel In rng
        cel.Value = CDate(cel.Value)
    Next cel
    Application.ScreenUpdating = True
End Sub

Sub Test()
    Dim rng As Range
    Dim parts() As String
    Application.ScreenUpdating = False
    For Each rng In Range(Range("D2"), Range("D" & Rows.Count).End(xlUp))
        If Application.IsText(rng.Value) Then
            parts = Split(rng.Value)
            If UBound(parts) > 0 Then
                rng.Value = DateValue(parts(1) & "-" & parts(0) & "-" & parts(2))
            Else
                parts = Split(rng.Value, "/")
                If UBound(parts) > 0 Then
                    rng.Value = DateSerial(parts(2), parts(1), parts(0))
                End If
            End If
        End If
    Next rng
    Application.ScreenUpdating = True
End Sub

Good morning Hans, thx so much for the speedy response.
When testing this I get a Run Time Error '13', see below
And here's a snippet of what the spreadsheet Col D looked like before running the VBA.

Would appreciate any further advise pls

  Could you attach a small sample workbook demonstrating the problem (without sensitive data), or if that is not possible, make it available through OneDrive, Google Drive, Dropbox or similar?

    Hi Hans, thx so much for your response and sorry for the delay, was on leave.
    I have an existing Macro that copies invoice data from various files together into one file.
    As you will see from the attached Demo file, sometimes the date comes across correctly and sometimes it doesn't.
    The count of headers tell me how many files it came from and I usually ignore these.
